Humanity would not realize they were talking to ETs online in their social media.

"where most intelligent life in the cosmos is uninterested in life on Earth because "down here", it's all below the threshold for what they consider intelligent life. Some good and interested specialists may make useful contact with worlds like this, and some bad imitators, and a lot of unrelated noise may also be made."

Humanity has no idea what the Earth is, let alone what the moon and space are, or even what ETs or gods are.

No idea whatsoever.

That is by design and intent. Sorta like a movie not spoiling itself, but does provide foreshadowing in novels.

Amongst the individual sub densities, each individual shard can be diametrically different from the youniverse of another sub density shard server.

For much of humanity, yes, "intelligent life in the cosmos" are uninterested. But that's because humanity is asleep and it is uninteresting watching an ant colony that is asleep.
